●
Measured frequency offset to the nominal frequency in kHz
●
Numeric frequency offset of measured power
●
Numeric power sensor level in dBm (if available; "NRP")
●
Bargraph indicating the power and a color-coded overload state, where:
–
red : overload state, check message
– yellow : power approaching overload state
– green : power in a valid range
●
If applicable: overload messages
Overload messages
The following messages indicate an overload:
●
"RF Overload"
Overload of the input mixer or of the analog IF path.
●
"IF Overload"
Overload of the IF signal.
●
"ADC Overload"
The dynamic range of the AD-converter is exceeded (clipping).
A combination of these overloads is also possible.
In all cases, set the RF attenuation to normal or low distortion (for RF input), or reduce
the input level.

5.1.3.2 IF Spectrum Preview
A preview of the measured spectrum (power level vs. frequency) for the IF (intermedi-
ate frequency) signal is provided. The center frequency is the nominal channel fre-
quency. The frequency range shows the measured bandwidth. The power range is
selected such that the noise level remains visible.
